Lexie B3
The Lexie B3 is a behind-the-ear OTC hearing aid priced at $999 that earns an A grade with a SoundScore of 4.8/5 in our lab testing. This places it at #1 among the 65 OTC hearing aids we've evaluated, making it a standout performer in its category. In our standardized testing, the Lexie B3 demonstrates excellent speech-in-quiet performance at 4.5/5, scoring 1.73 points above the OTC category average of 2.79/5. Speech-in-noise results are more nuanced—while the 2.5/5 score sits 1.02 points above the category average of 1.48/5, this remains mixed in absolute terms. Music streaming quality is solid at 3.3/5, exceeding the category average by 1.38 points, and feedback handling is excellent at 4.6/5. Own-voice comfort scores a solid 3.0/5, sitting 0.49 points above the category average. The device uses a tulip dome coupling in both initial and tuned configurations, maintaining consistent performance across fitting conditions with identical normalized scores of 4.8/5 for both fits. For those considering alternatives, devices like the RxEars Rxi, Meta Ray-Ban Glasses (Gen 2), and Cearvol Wave offer lower price points, though with correspondingly lower SoundScores. The Lexie B3 is best suited for consumers seeking top-tier OTC sound performance who prioritize speech clarity in quieter environments and quality music streaming, and who can accommodate its mid-tier OTC price point.

Signia Silk Charge&Go IX
The Signia Silk Charge&Go IX is a premium-priced invisible-in-ear prescription hearing aid currently available at $3,298. In HearAdvisor's lab testing, it earned a B grade with a SoundScore of 3.7/5, ranking #30 of 36 prescription hearing aids tested. This device delivers excellent speech clarity in quiet environments, scoring 4.6/5—a full 1.30 points above the category average. Speech in noise performance is mixed at 2.2/5, though still slightly above average for the category. Feedback handling is strong at 4.3/5, providing reliable stability during daily wear. The Silk Charge&Go IX has notable limitations. Own-voice comfort scores low at 1.5/5, falling 1.25 points below the category average—a consideration for users sensitive to how their own voice sounds while wearing hearing aids. Most significantly, the device scored 0.0/5 for music streaming, meaning it lacks practical streaming capability from phones or other devices. At this price point, competitors like the Phonak Sphere Infinio (5.0/5), Oticon Intent (4.85/5), and Signia's own Active Pro IX (4.67/5) deliver substantially higher overall sound performance. The Silk Charge&Go IX may appeal to users who prioritize an invisible form factor and strong speech clarity in quiet settings, but those who value music streaming or own-voice comfort should explore alternatives.
